[Bf-committers] The image of the full-screen mode is left in the background

[PerfectionCat]

Hi.

Blender 2.68a r60092
Windows XP/SP3 32bits
NVidia Geforce 9500GT

The image of the full-screen mode is left in the background when I return it to a window mode after having changed it to a full-screen mode from a window mode.
Is this malfunction?
Or is it caused by the driver whom I use?
